[Q] Nooks self-restore / downgrade? - Barnes & Noble Nook Tablet

Hello,
I have been looking for the answer all over but can´t find it.
I have 3 nooks, they all worked fine for 6 month, but this year in January they all automatic self restored them selves, and downgraded to the old version 2.0.2
I don´t know what happened or what could cause this problem, i did not press any restore buttons or install any software that would cause that, no addition SD cards or cables connected. Just woke up next day they all show me Set up Screen where i have to choose language , and connect to the internet, then they install them self, and i check the version and it´s old one..
After that i have to install about 2-3 updates, till i get to the 2.2 version
The only thing that i suspect is that they were all put together in to the same box, and could be that they press on each other THE N button , but would that trigger them to self restore ??
Thank you, i would really appreciate your help. Because i have more nooks and i am afraid if this could happen to them also one day.

The last version of firmware for the Nook Tablet (the Nook model discussed in these forums) are 1.4.3. Your Nooks most likely are HD or HD+, as the latest firmware for them are 2.2.x. You should post on your question on the forums dedicated to the HD/HD+: http://forum.xda-developers.com/nook-hd.
FWIW, a commonly known trigger for a Nook to get into a state leading to factory-reset is when it fails to boot/reboot 8 consecutive times.

Thank you for your answer, i am so sorry , didn´t realise that this is not NOOK HD forum (

I found amazing problem that works almost like magic.
So what happens is that i have 3 nooks , and to save some space i put all of the together in to the same box.
Now i have been doing some test and found out that When you put nooks on top of each other they will turn of the screens and can if you move them a little, they will turn on as well. So that could cause the problem that they would turn on / off so many times that that would lead to the boot / reboot / factory-reset.
It´s unbelievable that 1 nook is turned off can have EFFECT on the other one that is ON, it will wireless tell him to turn of the screen .
Here is the video :
I will post this in to the Nook HD forum

[Q] Root will me wifi, Now: Stuck installing ClockworkMod Recovery to install new ROM

Hello everyone,
first of all, I am new on this Android world, so, any basic question I post, I ask for understanding in advance.
Trying to root my Viewpad 7 (Froyo 2.2), I come across to GingerBreak, I run it and it sucessfully root but it killed my Wifi (that's all connectivity I used, I have no mobile data plan)
as I wanted also to try new rooms, and flash a new one seems to be a only solution for the wifi problem (I have try factory settings without success). I come across Rom manager,
I download and install ROM_Manager_Premium_v4.3.2.3.apk from SD
and download CleanViewpad7_signed_v1.0.zip to my sd card
If I try to flash ClockworkMod Recovery from ROM manager, i get:
"Error while downloading from the server. Please make sure you have a stable internet conection ..." but that's no possible as I have no WIFI in my viewPad7 after root!
If I try to Install ROM from SD card (from Rom manager), the device restore in "Recovery mode" of "Andoid system recovery <3e>"; and it brakes with message "E:signature verification failed".
I have donwload it from several servers (http://forum.xda-developers.com/showthread.php?t=1168562), and all give the same error mesaage
I try to search for manual mode to install clockwork (http://forum.xda-developers.com/showthread.php?t=755379) but I can not find a way to go.
"wipe data/factory reset" inicializate the device, but it doesn't help with the wifi. it keet saying scaning->disconected->scanning->disconected ... (and of course, my wifi conection is set to remember with the password memorized)
In the cofig menu, i can see:
baseband: PR3.7_128
Kernel Apps_2.6.32.9
Build 4027_3_16R
In the FTM mode:
SWver=3.16R
Model:FM6-0001
HWVer:106
what can I do?, I just have a 7inch no apps-no connection beautifull "thing"
More: I have try two other Rooms:
EUViewpadV1.4.zip
Viewpad7 Stock EU 2.2 +rooted+CWM.zip
nothing works, signature verification failed

Okay, you willl be fine - just need to flash & restore it first to factory/stock ROM first, then root it and go from there - here are the steps that I would suggest:
First, save anything important on your mSD card if you need to, perhaps to a USB drive and/or computer's hard drive.
Next, use this link http://forum.xda-developers.com/showthread.php?t=1260463 to download - for the stock ROMs from Viewsonic.
The newest one is for newer ITE hardware VPAD7 (and, I believe yours is NOT if you could get CleanViewpad v1.0 to boot up & activate the screen - and a number of users are having trouble with wifi ....) To override that signature verification error message that you get, look into CWM (I'm using v3.0.2.8) under Apply update from .zip file on SD card, and there's a "toggle signature verification" switch - change it and trying applying the zip file again to flash - it should work, as I recall. Before that, make sure you wipe system/cache/dalvik & reset data, etc. for a clean(er) new installation.
FM6-316Q-*.nb0 should work with earlier, non-ITE Vpad7 and so should FM6-3310-*.nb0, whereas the FM6-3350-*.nb0 should be for newer ITE devices with either HWver 107 and/or (some) HWver 106.
To flash it, you CANNOT use CWM but must download the SUTL3 (v1.7.9 worked for me) - read & following the onscreen warnings/directions and it should be finished in less than 10 minutes (have the Vpad7 fully charged first & do NOT need to have the mSD card installed)
When it's finished, reinstall the mSD card, take a deep breath & reboot/restart, and you should be up & running with the stock ROM in a few minutes - if so, check your wifi connectivity first before going any further. Start with 316Q ROM first and if it's good, you might want to move up to 3310 next (it's newer) & recheck wifi connectivity. STOP then, as yours is non-ITE and the 3350 will NOT work. You can then flash CWM and/or root it - with SOC or GB methods, etc. etc. which you're familiar with.
I had no problems with wifi connectivity and/or 3G data (prepaid GSM 3G coverage) running the Froyo Enhanced custom ROM (non-OC version since I have ITE hardware) OS 2.2 - However, I'm running stock ROM OS 2.2.2 rooted and wifi is perfect for me. (I'm written up a quck tip/guide also - in case you didn't come across it while searching for answers) http://forum.xda-developers.com/showthread.php?t=1264647
Lastly, TJ_Style's FM6 ROM w overclocked kernel should work for you as well, it's OS 2.2 but I patched the boot.img with my saved newer 2.2.2 ITE kernel and got it working too, and, no issues with wifi access at all.
In short, check & change your Signature Verification options under CWM and try again, and, if not - restore by reflashing with SUTL3 a factory *.nb0 file, then - proceed from there.
Good luck, have a bit of patience - it's both fun & exciting, challenging & disappointment often followed by the joy of luck & success. Let us know how it go & write down any error message(s) so we can help figure it out together - plenty of "newbies" been around but still stranded at times.
Regards -
Thanks, SUTL3_v1.7.9 and FM6-3310-0-5029-A02.nb0 works like a charm, easy and bring back my ViewPad7 to work,
for anybodies info, that change my ViewPad to:
Android version : 2.2.2 (from 2.2)
Baseband version PR3.7_128 (same)
Kernel Version Apps_2.6.32.9 (same)
Build Number 5029_3_310 (from 4027_3_16R)
I got encouraged, and I try FM6-3350-0-1008-A01.nb0, that gives me:
Android version : 2.2.2 (from 2.2)
Baseband version PR3.7_128 (same)
Kernel Version Apps_2.6.32.9 (same)
Build Number 1008_3_350 (from 4027_3_16R)
Swype included !! (seems a little odd and disordered the configuration process, so skip it)
what means ITI / non-ITI ?
languajes: both nb0 are English/Spanish/French only
now I will start with rooting and so, I will let you know
once more, many thanks.
Wonderful, we are all glad to know that you had success. Is your wifi working once again with either stock unrooted ROM?
Once rooted & CWM reinstalled, do a backup first to save those *.img files, etc. so that you can easily restore/go back later on if necessary.
As I said, check out Enhanced Froyo and TJ_Style's FM6 custom ROMs, both of them should work nicely for you - including wifi (I believe, as least on mine - both solid signals in both G and N routers, WEP & WPA-2 modes. (Also, try open or unsecured mode)
Happy flashing ....
YES !!, wifi is working back to normal. At least sometimes (I have need to re-flash few time already, it has stoped working few times more, and not becouse of rooting, just installing apps from market)
I have also encoutered the next problem : http://www.youtube.com/watch?v=6XuccAxXY_8
and that shouldn't be normal behaviour?, isn't it ?
try with diferent room or return to viewsonic ?
by the way, what ITE means ?
thanks once more

ITE refers to Panjit Touchscreen (Multi-Touch Resistive) used on newer Vpad7 built & shippped vs. older hardwares used on earlier models.
On that subject, I've looked at a # of youtube video reviews & posting about the device's orientation/rotation issues, and it seemed to me that it prefer to be in a landscape mode. But, there are times where we wanted to have a choice, turn it 90 degree for a vertical or straight up - not so sure it's 99% hardware problem - rather, problem caused by a mix of Android codes & Apps used. Some were defective but that's a production & quality control issue, so, anyway.
I'm not sure after seeing at your YT video what the problem is, please describe & I will have another look with my thoughts on it.
Does it happen with the stock/factory ROM or only with the ROM being runned now - I would flash a different ROM to compare the results.
Sending it back to Viewsonic is an option but you will be without its use for 2 to 4 weeks (usual timeframe, could be longer) & deal with packing, insuring, shipping & waiting - but, if it's "bad" - get authorization & exchange it or repaired.
Regards !
Bad news, as later day, wifi come alive, it went down sometimes, and as I was trying application I flash the three diferent factory rooms few times. What I didn't notice is that the wifo was disconecting more and more often: now it does connect at all.
As said, I have try the three diferent ROM in viewsonic, and also an app called FixMyWifi, nothing helps, wife is all the time "Connecting..."->"Disconected"->"Searching"->and so on
about the strange behiviour of the screen, the matter is that as soon as using two fingers, the right one, can not be in lower position than the left one. So forgot about plenty of games, drawinf with two fingers, dificulto for rotating maps (when the rotation of finger goes beyond 90 degres)
And one of the reasons I bought it is my little boy, explain that to a children of four years..., in deed he found it as "that does work well, the tank does not follow my fingers"
so, as a multitouch is basically pointless if you have to care your right finger does not go bellow your left one ...
Anything to do with the Wifi ?
rooting may help in some way?, and some terminal comands?
I am willing to try, I am just in the point before return it as faulty device.
Many thanks for all the help given.

Thanks for clarifying and I looked at the YT video again - perhaps you would be better off getting Viewsonic for authorization to return for repair or exchange it. On my device, the screen is responsive 98% of the time but I do realize that sometimes, when we're playing Angry Birds, that it too doesn't always readily respond to commands or launch the bird shots .... Not a big deal for games, it will usually get going again - worst case, use the Go Back key & restart the level - I figure that it could be a combination of the Froyo or Android codes written for the OS and/or along with the Angry Birds gaming itself.
Afterall, my "regular" & 2 years old smartphone, HTC Eris running a nearly identical CPU & configuration is running custom rooted GingerBread ROM - and, is must better & responsive in overclocked mode. The Vpad7 will not, I feel, be running Honeycomb but let's hope that some of the veteran xda developers will soon release a working GingerBread ROM - perhaps it will fix many of the issues across the field, so to speak. (or, if Viewsonic will release it as official update .... wishful thinking, huh - but !)
On the wifi issues, have you tried doing the SuperOneClick and/or GingerBreak apk to root, and then flash TJ_Style's custom FM6 ROM - http://forum.xda-developers.com/showthread.php?t=1264647 - this OC version with WiFi fix might work for you without any mods (patching or zip flashing the 2.2.2 boot.img)
On wifi configuration itself, is this happening with different routers - "older" G mode or newer N (faster) routers, unsecured or open network or secured (WEP, WPA or WPA2, etc.) - any issues on the host computer/router's firewall blocking ? Can you log in at a public hotspot or cafe like Starbuck ?
Go into Settings > Wireless & network settings > Wi-Fi settings > and, then, tap the Home key (the bottom of 4 keys on the device - held in landscape mode) and you should see "Scan" & "Advanced" - does it pickup a decent signal ? Click "Advanced" & look at your "Wi-Fi sleep policy" - mine is checked for "When screen turn off" - tried "Never" or "Never when plugged in" - any difference ? If you get this far, you might want to try to set up & Use "static IP" instead of using dynamic ip addressing that these devices usually count on .... it's a bit of work, but might help to "zoom" into your own router only.
I use "Wifi Analyzer" v2.5.13 from Kevin Yuan (Google Market) to help scan the spectrum for signals and possible interference, which sometimes do happen - and moved 1 of our 2 cable broadband router to a different channel so that all of our wireless (up to 15 of them, yes) devices around the house can easily connect to the hotspots. (Reading posts @ other forum sites & ran my inSSIDer v2.0 from Dell laptop for baseline, it scanned 17 active APN's with varying signal strengths, our Sony W995 picked up only 6 signals with 3 good ones, the HTC Eris picked up 6 signals also with 3 good ones, and the Vpad7 only 3 signals, 2 of them from our own indoor G & N routers plus 1 from neighbors that's marginal. It's safe to assume that our device's internal radio receiver or Baseband isn't very good with reception to begin with - you might need to flash a different "build" like mine to give it a try - and try switching your wifi channel.)
Just some of my thoughts on the wifi problem as I do run into signal problems myself every so often installing a new device or configure a guest's new gadget at home. If all else failed and along with the touchscreen problem, then I would say get it fixed via repair or exchange from Viewsonic, and then .... (a few weeks later, upon its return to you - happy rooting & flashing, etc.)

about the wifi issue, I have try all the steps you mention before, nothing helps with my router (deliver by the telephone company). The only thing that works, sometimes, s turning off the router for several seconds, then it connect again. As absurd it sounds, it looks like the viewpad doesn't disconnect from the router even as turned off, so the router doesn't allow to negociated again a conection (and it keeps it in connected device while the viewpad is reseting or turned off)
I have try connecting a Linksys Wi-fi and connecting trought it : WORKS GREAT.
Trying in different locations, some of them same problem as the router, others works perfectly.
Solved for home with second wifi-point, I see myself one day asking Starbuchs guy to reset their router...

[Q] Tablet WiFi Switches Off

There have been loads of Posts about Android WiFi switching itself off, affecting various devices. The scenario is that the WiFi switches off spontaneously after previously working OK. Try to switch it back on, and it will switch off again after about 10 seconds.
I have tried ALL the suggestions posted in various forums but regrettably the only solution so far has been to reinstall the device Firmware.
This has happened to me twice now, so I'm trying to find a solution before it happens again which does not involve a Firmware reinstall, with the associated aggro of reinstalling Apps and setting everything up again.
SURELY there must be a method of re-initialising the WiFi via ADB or the Terminal Emulator, or something similar !
The machine in question is a Dropad A8 tablet, originally running Android 2.3 and now Android 3.0 Honeycomb. Like I said before, this has happened with both Firmwares, now on two (total) occasions.
Over to you, boffins !:good:

Thanks for your reply.
The problem arose again yesterday evening, thankfully after I had downloaded + installed fxr wifi, plus another similar app.
Sadly neither worked, so I was stuck with doing yet another firmware install. This time I chose Android 2.3 (Genesis 3 ROM v2.1.1) which is the same as we run on another identical tablet here, and has never given problems. (Previous firmware was Android 3.0, Genesis 3)
The reinstall went OK and the WiFi started to work again ...
Any more ideas ?

[Q] Problem after update to ICS

I have a problem with Huawei Mediapad s7-301u after update to ICS. Everything works fine but when I finish for example with game and put tablet in standby my tablet turn off completely and I must turn on tablet again. Factory reset doesn't help. Flashing rom again doesn't help also. Any solution?
"I have a problem with Huawei Mediapad s7-301u after update to ICS".
Just a couple (or more) of questions , which ROM ICS are you using exactly on your MediaPad, i.e. stock ICS, AOK? (presumably not CWM 10.1 ,CWM 10.2 nor Evervolv as they are Jellied Beans and later) maybe Hwmod Under/Overclock - B0005 to B010.
"Standby" means just tap the power switch, or did you power off'? If not what is standby? TWRP?
If power off did you rename/delete the dload folder on your exSdcard, and last but not least why factory reset? Flashing ROM again, why ,which and how - step by step please let me know.
(I presume you deleted the old rom from the exSdcard) and or recovery.img
If you have powered down the tab, on power on, it should after ten seconds , turn on.
As there are so many "STOCK" roms available, try Settings, About Tablet to clarify, ), scroll down, "Build Number" is S7-301........................"
I am getting confused with some 10 threads as to which ROM is the best for my old Mediapad, but I see no reason why a stock rom would behave as such.
If I can help, reply

I remove microsd from tablet. I don't use it. Factory reset because I have problem and I tried to fix on this way. Flashing ROM with instructions from huawei official page.
Honeycomb works without any problem.

I have no problem with B005 nor B010 (Both HwMod´s original root and the overclocked kernel version)
Have you tried these?
Tthe simple download , unzip , copy dload to card , reboot, take out card and power off
for ten seconds after the droid blacks out?
It took me a while to to get it right - as in I loaded o.k. then powered off too soon, then tried again - but it´s working fine for 4 months now.
(not forgetting to rename dload, of course!!)
Hope this helps, also checkout androidiani.com for hwmod´s old threads if the downloads aren´t here

Solve Display init failures by Android update?

Dear Experts,
Months ago my 2y old XZU on 4.4.4 (6833, towel rooted, locked, CWM recovery) started to fail on init of LCD, when coming out of standby. LCD init not only fails when device gets waked up by "power" button, but also when power is applied (Dock connector or USB). So I guess in fact it is a firmware issue (not a defective power button or the like).
It gets worse and worse; when device is warm it sometimes needs 30 or more off/on cycles.
When LCD init fails, the screen either stays black (only backlight) or colored lines show up shortly and fade away. But in fact the device is running - only LCD is not working.
But when init is successful, the XZU can run nicely for hours (as navi).
I hope that a android FW update might help!?
Unfortunately OTA doesn't seem to work on routed devices even with still locked boot loader.
Is there a way to update directly to 5.1.1 available now? Is it possible to update in two steps?
I would not mind to loose root, but loosing the possibility to write to external SDCARD!
Any help/ideas? THANKS A LOT!

Sounds like SOD, or Sleep Of Death. The Ultra had some issues with it back on Jelly Bean, but I hardly read about it being an issue on KitKat, but yeah, it's probably a software issue, so an update to 5.1.1 might just cure it. You have a couple of options here:
1. Update the official way by installing Sony's PC Companion app on your computer and updating it that way
2. Update it in a little less official way by updating it manually yourself with Flashtool on your computer
3. Update by flashing a customized version through a recovery system on your device (like CWM or TWRP)
I would personally update it through PC Companion if I were you, since I guess you're not that technical when it comes to flashing and troubleshooting things. PC Companion should notify you about the update as soon as you plug your Ultra to your computer. If it notifies you about the 5.0.2 update, then I guess you'll have to update to 5.0.2 first, and then you'll be able to update to 5.1.
Flashtool allows you to manually download a FTF, or the ROM file from XDA and then flash it yourself. It's a lot quicker than PC Companion, but also a lot more complicated for people who haven't used it before.
Flashing through a recovery is mainly for people who already are used to flashing and stuff like that, and know what they're (mostly) doing.
Any other questions?
Thanks for your very valuable hints!!!
I'm really curious if it will work with PC comp (vs. OTA) and if I will loose write access to SDRAM (introduced in Android 4.4 and regained by root and SDFix).
Currently the download is running..
Will post results

The OTA will only tell you to connect to the computer to update. And regarding SD-card, that won't be an issue. Android will ask you to grant permission to the SD-card in some cases, but I haven't had any issues with it. Most if not all file explorers works just fine, and you won't experience any issues with the SD-card.
The update worked (no error on PC), but device seemed dead afterwads
After a reset and numerous power off/on cycles, the LCD init worked and I could see the result. :laugh:
Root was gone, of course. Recovery system and write access to SDCARD, too. Therefore Sygic app (navi), which had been moved to ext. SDCard. could not run anymore and moved itself to .android again.
But worst of all: the init of LCD now works even more seldom!
It does not even work when device has been shut down before, cooled down and is then switched on.
As far as I read, the SOD is different, cause my device in fact is "awake". It runs fine - only LCD is not working and not displaying anything.
I have no idea how to fix this. I can not imagine any hardware defect, causing such behavior (and I designed embeded systems with gfx controllers, myself).

But that does sound like a hardware issue. The final thing you can do, before you'll have to send it in for repairs, or get a new device, is to do a full factory resetting and see if that finally helps. You just updated now, but there's still a lot of crap left over from the previous version, that might screw things up.
So my advice would be to do a wipe, check if it help, and if not either send it in for repairs or get a new device. It's not a software issue if the issue travels over several OS versions with you. It may be a faulty display connector.

Huawei Honor Pad 2 unable to connect to Wifi after system update

Hi, this is my first time posting on xda forum, so if my post has some problems, I'd be delighted to correct.
So, I bought the Huawei Honor Pad 2 tablet about a year ago, and about last month it asked me to upgrade the system, and after the upgradation, the wifi icon becomes greyed out and I'm unable to turn it on. I tried to factory reset and wipe its cache partition but still no luck.
I dont know whether to flash its firmware would solve the problem but a few sites I stumbled upon, none of the links works(e.g. huawei-firmware rom links for my tablet model number don't work)
Some searches suggested it could be my hardwares malfunctioning, but since the wlan option greyed out problem only occurred immediately after the system update, I wonder if reflashing a new rom would work.
So I have run out of ideas, also I could not find honor pad 2 on the official huawei website, nor on xda forum, it mostly gives me mediapad as a result, but they seem different on pictures.
And some specs about my tablet:
Model: JDN-W09
Build Number: JDN-W09C233B023
EMUI Version: 4.0.3 (can't remember the original version but this is the one I got after that horrible system update)
Any helps are greatly appreciated!

Hi,
I had the same update,and we have the same specs,but tell me please how did you manage to get google play and all other google things to work?Maybe its because you are rooted?
It seems we are the only ones that we have this tablet,cos i can't find anything about rooting it or solve the google play problem without rooting.The worst thing is that nobodys bothering to make a post about it cos maybe the tab had been bought by a few people.
I don't have your problem,mine is working ok but my problem is way greater.I have done cache clears,download and intstall google services several times and some other tricks that i found on the net but nothing seems to work.
One click rooting methods:none of them work!
The οnly sure thing that we both need is a guide of how we are going to update the firmware to an earlier version(stock firmware)
Here on XDA i found only guides for phones of honor or tabs like media pad m2 that they seem to be similar but yet...i'm not sure.
I hope someone will take the time to answer on your post and our problems with this awesome tab!
I have also upgraded my Honor Pad 2 JDN-AL00 model to EMUI 4.0.3 B023 latest firmware and faced similar issues of Google apps not able to run anymore. I have tried to rollback the update by reflashing with older firmware versions. The update process shows success but when I boot up the set it still shows B023.
After researching the net, I think the problem could be because the older firmwares found in huawei-firmware.com are all OTA which means they are incremental updates. To fully rollback to earlier versions, I think we need Full OTA firmware. So far the only one that I can find on the net is B018 version. It’s abt 1.7GB. I have not gotten down to test out my theory. If you’re keen you can give it a shot and let everyone here know if it works...
